Specification of Letters' Patent No. 12,422, dated February 20, 1855.

To all whom it may concern Be it known that I, SAMUEL TAGGART, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and Improved Mode of Feeding Flour-Bolts; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is an end View of two flour bolts with my improvement applied to them. Fig. 2, is a vertical section of the annular chamber, and hopper boy the flight arm above not being bisected. Fig. 3, is a plan or top view of the flight arm, hopper boy and annular chamber.- Fig. 4', is a detached view of a portion of one of the bolts and the spout which conveys the flour from the annular chamber to the bolt.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and improved mode of feeding flour bolts whereby the meal is fed at all times equally and uniformly to the bolt as will be presently a circular platform B technically termed a hopper-boy in the center of which is.

fitted an annular chamber C, see Figs. 1, 2

and 3, provided with a cover (at) having two apertures (72) (b) in it near its edge and at opposite points to each other as shown in Figs. 2 and 3. v

D is a vertical shaft which passes through the center of the hopper-boy and annular chamber C. To the shaft D are attached sweeper arms (0) having sweepers secured to their ends, said sweepers being within the annular chamber C as clearly shown in Fig. 2. On the shaft D directly above the hopper-boy B there is placed loosely a flight arm E having flights (e) secured in an oblique position to its under side as clearly shown by the dotted lines in Fig. 3.

F is a rod which passes horizontally through the shaft D and has cords (f) attachedto its ends said cords being also connected to the ends of the flight arm as shown in Fig. 1. v

G, G, are spouts which lead from the lower part of the annular chamber C to the elevated ends of the bolts A, A, see Figs. 1 and 4. The upper ends of these spouts are provided with slides (g) as shown in Figs.

1 and 2.

' At the lower end of the shaft D there is a toothed wheel H which gears into a pinion I at the upper end of a shaft J, the shaft J having a bevel wheel K at its lower end and which gears into a bevel wheel L on a horizontal shaft M,"see Fig. 1. At each end of the horizontal shaft M, there is a bevel wheel N, these bevel wheels gear into bevel wheels 0, at theends of the bolt shafts P.

Operation. The meal to be bolted falls upon the hopper-boy B and as the shaft D rotates motion is given the flight arm E in consequence of its attachment to the rod F by the cords (f). The flights (e) as the arm E rotates carry the meal toward the center of the hopper-boy B and it falls through the openings (6) (6) into the an-.

nular chamber C, the meal being cooled in its passage from the periphery of the hopper-boy to the annular chamber. The sweepers (d) (d) as they revolve force the meal from the annular chamber G into the spouts G, G, which convey it into the elevated ends of the bolts A, A.

By the above invention the meal is fed in a regular and uniform manner to the bolt-s and .is in consequence perfectly bolted. The usual method of feeding the meal to the bolts is by means of spouts with a drop shoe under each spout. A shake motion is given the drop shoes by means of cam or wiper wheels which cause the meal to slide down the incline bottoms of the drop shoes whence it is conducted into the bolts through ordinary spouts. The drop shoes supply the bolts very irregularly with meal as the jar of the shoes condenses or packs the meal in the large spouts over them andwhen the slides or gates are drawn a large quantity of meal rushes into the bolts which is in consequence not only imperfectly bolted, but is the cause of sending forward so much o-fi'al, returns etc. to the subsequent machinery, that the elevators, conveyers and spouts are frequently choked. This difficulty is avoided by my improvement, the feeding as previously stated being equal and uniform at all times.

I claim neither the hopper-boy nor 5 the flight arm with flights attached sepa; retely for they have been previously used.

What I do claim as new and desire to se cure by Letters Patent, is,

I claim the combination of the annular chamber'C, with its sweepers (d) (d) as arranged for the purpose set forth.
